Abstract

fetched live from OpenAlex

BACKGROUND: Neutrophil-to-lymphocyte ratio (NLR), if elevated, is associated with worse outcomes in several malignancies. OBJECTIVE: Investigation of NLR at baseline and during therapy for metastatic renal cell carcinoma. DESIGN, SETTING, AND PARTICIPANTS: Retrospective analysis of 1199 patients from the International Metastatic Renal Cell Carcinoma Database Consortium (IMDC cohort) and 4350 patients from 12 prospective randomized trials (validation cohort). INTERVENTION: Targeted therapies for metastatic renal cell carcinoma. OUTCOME MEASUREMENTS AND STATISTICAL ANALYSIS: NLR was examined at baseline and 6 (± 2) wk later. A landmark analysis at 8 wk was conducted to explore the prognostic value of relative NLR change on overall survival (OS), progression-free survival (PFS), and objective response rate using Cox or logistic regression models, adjusted for variables in IMDC score and NLR values at baseline. RESULTS AND LIMITATIONS: Higher NLR at baseline was associated with shorter OS and PFS (Hazard Ratios [HR] per 1 unit increase in log-transformed NLR = 1.69 [95% confidence interval {CI} = 1.46-1.95] and 1.30 [95% CI = 1.15-1.48], respectively). Compared with no change (decrease < 25% to increase < 25%, reference), increase NLR at Week 6 by 25-50% and > 75% was associated with poor OS (HR=1.55 [95% CI=1.10-2.18] and 2.31 [95% CI=1.64-3.25], respectively), poor PFS (HR=1.46 [95% CI=1.04-2.03], 1.76 [95% CI=1.23-2.52], respectively), and reduced objective response rate (odds ratios = 0.77 [95% CI=0.37-1.63] and 0.24 [95% CI=0.08-0.72], respectively). By contrast, a decrease of 25-50% was associated with improved outcomes. Findings were confirmed in the validation cohort. The study is limited by its retrospective design. CONCLUSIONS: Compared with no change, early decline of NLR is associated with favorable outcomes, whereas an increase is associated with worse outcomes. PATIENT SUMMARY: We found that the proportion of immune cells in the blood is of prognostic value, namely that a decrease of the proportion of neutrophils-to-lymphocytes is associated with more favorable outcomes while an increase had the opposite effect.

Teacher imitation

Not calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
